Electrolux AC: Cooling Diagnostic Assessment 1
Reported Problem: Customer in ATS Advantage, Ahinsa Khand 1, Indirapuram reports Electrolux UltimateHome inverter AC displays E4 and stops cooling.
Customer: 'Electrolux AC chalate hi thodi der me E4 code dekar band ho jata hai.'
Technician: 'E4 indoor blower motor ke speed feedback ka issue hai sir. Hum motor aur control board check karenge.'
Technician Checks: Multimeter test showed motor windings were healthy, but the Hall sensor circuit was dropping pulses due to fine dust lint on the magnet ring.
Repair Approach: Cleaned motor rotor assembly, lubricated end bearing, and verified smooth 5V square wave pulse feedback.
